Specification of Letters Patent.

Patented Jan. 33, i 914. Serial No. 716,963.

To all whom it may concern:

Be it known that 1, JOHN A. Plan, of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Conveying Apparatus, of which the following is a specification.

My invention relates to improvements in conveying apparatus and especially to conveying apparatus employing a carrier for carrying telegrams, papers similar to telegrams, or other articles.

In the accompanying drawings: Figure l is a side elevation of a conveying apparatus showing a telegram about to be inserted into the carrier for transmission at one end of the line. Fig. 2 is a side elevation of the carrier. Fig. 3 is a top plan view of the carrier. Fig. 4 is a perspective view of the plunger used in the carrier. F 5 is an end view of the carrier.

Like letters of reference refer to like parts throughout the views.

The track or way C is supported at one end by the hanger A and at the opposite end by the cross rod A carried by the hanger A. Secured to the propelling mechanism at each end of the way at A and A is a wire C for supporting the propelling mechanism when in operation. Carrier B is adapted to travel on the way C and is propelled upward from one station by the cord propeller B operated by handle B This cord passes over the pulleys B and 13* in the forward frame of the propelling mechanism and is adapted to engage the carrier as shown in Fig. 1. This wheel propelling mechanism may be of any suitable construction and arrangement.

The carrier consists of an upper frame 1 carrying the wheels D which are adapted to travel upon the track 2. Suspended from the upper frame work 1 is a cylinder 3 open at both ends and provided with a slot E in its upper surface. Adapted to move within the cylinder 3 is a plunger F having the heads F and F connected by a link F This link extends up through the slot E and is provided with a lug 4c having rubber bumpers 5 at each end, and the object of these bumpers is to stop the sudden jar when the plunger is forced to the farther end of the carrier as hereinafter mentioned.

The operation is as follows: When the carrier is in the position shown in Fig. 1 in full lines the plunger is at the lower end of the carrier so that a telegram B or other paper can be inserted into the open end of the cylinder By pulling on the handle 13 the propelling mechanism shoots the carrier up the line C until it comes in contact with the rubber spring G carried by the track G supported by the rods G connected to the support carried by the cross arm A The carrier striking the rubber spring G is checked in its progress along the way, but the contact with this rubber spring causes the plunger to move forwardly, and in the present instance, upwardly, with respect to the carrier parts in engagement therewith, by its momentum and hence automatically to eject the article into the hopper H from which it passes down tl'irough a chute co1n posedof metal chains H to a place of deposit. If the propulsion of the carrier should be stronger than necessary, the rubber spring G would yield against the force of the carrier and the carrier would be stopped by the fixed rubber spring J. "When the carrier B strikes the rubber spring G and discharges the carrier, the rubber spring G reacts and drives the carrier down the wire way 0, thus assisting gravity in the travel of the carrier down the line. \Vhere the line is level telegrams can be sent from one end to the other.

I do not limit myself to the arrangement and construction shown, as it may be varied without departing from the spirit of my in vention.

In the preferred embodiment of my invention, exemplified in the drawing, I particularly desire to call attention to the coaction between the article to be conveyed, when the latter is of elastic sheet material such as paper, and the walls of the carrier receptacle; the sheet of paper tending to expand and thereby pressing itself outwardly against these walls and by its frictional engagement therefore prevent inadvertent displacement of the sheet from the carrier.

Having thus described the nature of my invention and set forth a construction embodying the same, what I claim as new and desire to secure by Letters Patent of the United States is:

1. In a conveying apparatus, a track or way, a despatching station and a receiving station at opposite ends of the way, a carrier adapted to travel on said way and provided with an opening to receive an article to be conveyed, and means on said carrier for ejecting said article upon its arrival at the receiving station.

2. In a conveying apparatus, a track or way, a despatching station and a receiving station at opposite ends of the way, a carrier adapted to travel on said way and provided with an opening to receive an article to be conveyed, means on said carrier for ejecting said article upon its arrival at the receiving station, and a chute at the receiv ing station for receiving the ejected article.

3. In a conveying apparatus, a track or way, a despatching station and a receiving station at opposite ends of the way, a carrier adapted to travel on said way and provided with an opening to receive an article to be conveyed, a plunger located on said carrier for ejecting said article upon its arrival at the receiving station, and a chute at the receiving station for receiving the ejected article.

4;. In a conveying apparatus, a track or way, a despatching static-11 and a receiving station at opposite ends of the way, a carrier adapted to travel on said way and provided with an opening to receive a telegram or other memo, a plunger located on said carrier for ejecting said article upon its arrival at the receiving station, a yielding buffer with which said carrier contacts to operate said plunger, and a chute at the receiving station for receiving the ejected article.

5. In a conveying apparatus, a track or way, a despatching station and a receiving station at opposite ends of the way, a carrier adapted to travel on said way and provided with an opening to receive an article to be conveyed, and means on said carrier for ejecting said article upon its arrival at the receiving station, said means comprising a part displaceable with respect to said carrier by its own momentum, when said carrier arrives at said station.

6. In a conveying apparatus, a track or way, a despatching station and a receiving station at opposite ends of the way, a carrier adapted to travel on said way and provided with an opening to receive an article to be conveyed, means for checking the progress of said carrier at said receiving station, and momentum actuated means on said carrier for therefore ejecting said article.

7. In a conveying apparatus, a track or way, a despatching station and a receiving station at opposite ends of the way, a carrier, the walls of which are adapted to coact with an elastic sheet disposed therein and to be conveyed thereby, to retain said sheet during conveyance, and momentum actuated means for ejecting said sheet upon the arrival of said carrier at said receiving station.

8. In a conveying apparatus, a track or way, a carrier having apertures at both ends thereof and adapted to travel to or fro on said way, means for projecting said carrier along said way, means for checking the progress of said carrier, and means for automatically unloading said carrier, when its progress is checked by said last mentioned means, through one or the other of said apertures according to the direction of travel of said carrier along said way.

9. In a conveying apparatus, a track or way, a carrier having apertures at both ends thereof and adapted to travel to or fro on said way, means for projecting said carrier along said way, and means for checking the progress of said carrier at two determined points in said way, said carrier adapted to automatically unload itself at one or the other of said points through the corresponding aperture therein, according to the direction of travel of the carrier along said way.

10. In a conveying apparatus, a track or way, a carrier having apertures at both ends thereof and adapted to travel to or fro on said way, means for projecting said carrier along said way, means for checking the progress of said carrier, momentum actuated 'means for automatically unloading said carrier, when its progress is checked by said last mentioned means, through one or the other of said apertures according to the direction of travel of said carrier along said way, and means adapted to co-act with said carrier unloading means to reduce the shock of operation of the latter.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses, this sixteenth day of August A. D. 1912.
